1 Corinthians 9:15

But I have used none of these things: (10) neither have I written these things, that it should be so done unto me: for [it were] better for me to die, than that any man should make my glorying void.

(10) He takes away occasion of suspicion by the way, that it might not be thought that he wrote this as though he was demanding his wages that were not payed him. On the contrary, he says, I had rather die, than not to continue in this purpose to preach the Gospel freely. For I am bound to preach the Gospel, seeing that the Lord has given and commanded me this office: but unless I do it willingly and for the love of God, nothing that I do is to be considered worthwhile. If I had rather that the Gospel should be evil spoken of, than that I should not require my wages, then would it appear that I took these pains not so much for the Gospel's sake, as for my gains and advantages. But I say, this would not be to use, but rather to abuse my right and liberty: therefore not only in this thing, but also in all others (as much as I could) I am made all things to all men, that I might win them to Christ, and might together with them be won to Christ.
